Abstract:
The present invention relates to an interior automotive part prepared from a thermoplastic composition comprising:
from 48-95 wt. % heterophasic propylene copolymer consists of i) a propylene-based matrix, and ii) a dispersed ethylene-α-olefin copolymer comprising ethylene and at least one C3 to C10 α-olefin;
from 0-20 wt. % ethylene-α-olefin elastomer comprising ethylene and at least one C3 to C10 α-olefin;
from 1 up to 30 wt. % high aspect ratio (HAR) talc as a filler;
from 0-5 wt. % of another talc;
from 0.05-1 wt. % phenolic antioxidant additive;
from 0.05-1 wt. %, amphiphilic protective additive comprising a hydrophilic part and a hydrophobic part; and
from 0-3 wt. % additional additives. It moreover relates to a method of producing these and to the use of such a composition for the manufacture of an interior automotive part in automotive applications.
